TRACK-SANDING DEVICE FOR LOCOMOTIVES.

SEECIFIGATION forming part of Letters Patent No. 700,924, dated May 27, 1902.

Application tiled .Tune 24, 1901. Serial No. 65,867. (No model.)

1'0 tl/f whom it muy concern:

13e it known that l, BERNHARDT HENRIK- SON, residing at Austin, Cook county, Illinois, have invented certain new and useful Improvements in Track-Sanding Devices for Locomotives, of which the following is a specification.

My invention relates to track-sanding devices for locomotives; and its object is to provide a simple, efficient, and reliable device of this character whose advantageous features of construction and operation will be apparent from the description hereinafter given.

The present invention is designed as an improvement upon that described and claimed in an application tiled by me on February 11, 1901, Serial No. 46,811, since issued as Patent No. 676,892, dated June 25, 1901.

In the accompanying drawings, Figure 1 is an elevation of a portion of a sand-box and boiler and illustrating my improved tracksanding devices, certain of the parts thereof being shown in section; Fig. 2, a sectional elevation on line 2 of Fig. 1; and Fig. 3, a sectional plan View of the sand-box, showing the positions of the sanding devices therein.

The sand-box 1 may be of any suitable construction,the one herein illustrated representing a form in common use having the vertical side walls 2 and the inclined bottom 3. The front sand-pipes a open at their upper ends through the bottom of the sand-box on either side thereof and extend downward upon opposite sides of the boiler 5 for supplying the sand to the rails in front of the front drivers in case the locomotive should be moving forward. The upper ends of these sandpipes are normally closed by hand-operated valves G,here shown as horizontally-swinging, which valves are secured to vertical spindles 7, journaled in the bottom of the sand-box, and having secured to theirlower projecting ends suitable means, such as shown in my said patent, adapted to be actuated from the cab by the engineer, whereby the valves 6 may be operated at will instead of or as supplemental to the ejecting devices hereinafter described. As herein shown, the hand-valves each carry a Siphon or Siphon-shaped passage S, whose longer leg communicates through the valves and is open and in communication with. the sand-pipe when the valve is in the same manner as in the pipes 11.

closed. Each sand-pipe is provided, preferably at a point remote fromthe sand-box, with an ejecting device or nozzle 9, to which Huid-pressure, air, or steam is admitted from a supply-pipe 10, controlled by the engineer in any suitable way. As shown more clearly in Fig. 2, a supplemental pipe or passage 11 communicates with each sand-pipe 4 below the valve G, but above the ejecting device, and eX- tends substantially horizontally through the vertical side wall of the sand-box. These pipes 11 project into the sand-box a considerable distance beyond the side wall in order to prevent the sand from accidentally falling or shaking out of the box, and their extreme ends are beveled or cut or formed on the bias, so that the extreme point overhangs the opening. By reason of this particular construction of the end of this pipe a comparatively large opening is presented for the exit of sand, whereby clogging is effectually prevented. The admission of air or steam to the ejectingnozzle causes a downward suction through the sand-pipe, whereby the sand will be sucked from the sand-box through the supplemental pipes 11, (also through the siphons 8, if used,) through the sand-pipes, and then inally delivered to the rails. It is obvious that the siphons 8 may be dispensed with and the sand ejected wholly through the pipes 11.

The particular sand-discharge pipes just described are the front Sanders, because they lead to the front of the drivers. Back sanddischarge pipes are also employed, and, as usual, such pipes 12 extend on each side of the boiler downward, so as to discharge sand behind certain drivers. In the particular construction herein shown, which is now considered the preferable one, the upper end of each pipe 12 enters the bottom of-a casing 13, whose Lipper end communicates with the sandbox by means of a pipe 14, which is projected into the sand-box a considerable distance and is at its extreme end beveled or on abias This casing contains an ejecting device or nozzle 15, pointing downward into thesand-pipe 12 and receiving fluid-pressure, air or steam, through a supply-pipe 16, controlled. by the engineer. It is evident that the admission of IOO pressure through the iluid-pressure-supply pipe 16 will cause a blast downward through the sand-pipe 12 and create a vacuum above from the sand-box through pipes 14 and delivering the sand onto the rails behind the back drivers.

As is well known, some locomotives are provided with two independent sand-boxes, in which case each of such sand-boxes may be equippedvwith the sanding device hereinbefore designated as the front sander,7 and the back-up sander may then be dispensed with.

I claim- -1. In a track-sanding device, the combination with a sand-box, of a sand-pipe projecting into the sand-box and having its inner end within the box formed on abias or bevel, and means for forcing sand from the box and through said pipe; substantially as described.

2. In alocomotive tracksanding device,the combination with a sand-box,of sand-pipes projecting into the sand-box and having their eXtreme inner ends on a bias 0r bevel and ejecting devices arranged in said pipes intermediate of their length; substantially as described.

3. In alocomotive track-sanding device the combination Vwith the sand-box, of sand-pipes projecting into the sand-box and having their extreme inner ends on a bias or bevel with the point overhanging the opening of such pipes and ejecting devices arranged in said pipes intermediate of their length; substantially as described.

4. Inalocomotive track-sanding device,the combination with the sand-box, of sand-pipes communicating with the sand-box, hand-operated valves controlling the upper ends of said pipes, supplemental pipes communicating with the sand-pipes below said valves and with the sand-box and ejecting devices arranged in said sand-pipes at a point below their communication with said supplemental pipes, substantially7 as described.

5. In a locomotive track-sanding device the combination with the sand-box, of sand-pipes communicating with the sand-box, handoperated valves controlling the upper ends of said pipes and provided with Siphon-like passages, supplemental pipes communicating with the sand-box and with the sand-pipes,

and ejecting devices arranged in said sand-V pipes at a point below their communication with said supplemental pipes; substantially as described.

6. In a locomotive track-sanding device the combination with the sand-box, of sand-pipes communicating with the sand-box, hand-operated valves controlling the upper ends of said pipes, supplemental pipes projecting into the sand-box with their extreme inner ends beveled or on a bias and communicating with the sand-pipes, and ejecting devices arranged in said sand-pipes at a point below their communication with said supplemental pipes; substantially as described.

7. Inalocomotive track-sanding device,the combination with the sand-box, of sand-pipes communicating with the sand-box, hand-operated valves controlling the upper ends of said pipes and provided with Siphon-like passages which are open when such valves are closed, supplemental pipes projecting into the sand-box with their eXtreme inner ends beveled or on a bias and communicating with the sand-pipes, and ejecting devices arranged in said sand-pipes at a point below their communication with said supplemental pipes; substantially as described.
